' 2Claims.

The present invention relates to an electrical terminal, and morevparticularly a terminal especially adapted for use in connection withstorage batteries.

It is well known been on a battery post of time, the terminal ingextremely difiicult for that after a terminal has a considerable periodbecomes corroded, it beto remove from the post,

resulting in many instances in the damaging of the battery,

and it is one of the objects of the present invention to provide abattery terminal which is adjustable to acco battery post, and one gagethe binding post trical connection and mmodate any size of which willpositively 'en-' providing a positive elecwhich can be removed withoutthe necessity of wrenches or causing damage to the battery.

A still further important tion is to provide a battery acter which ischeap easy to install on a remove therefrom.

In the accompanying object of the inventerminal of this chartomanufacture, relatively battery post, and easy to drawing whereincorresponding reference :numerals designate corresponding partsthroughout Figure l is a tery terminal illustrating the same,

adjustable lever which is piv- In the accompanying drawing wherein forthe purpose of illustration there is shown a preinvention, the referencenumeral 6 generally designates the terminal body which includes anreceiving socket or clamp one side thereof at ID as annular battery post8 which is split on clearly illustrated in Figure 4. The annular clamp 8is provided with a tapered bore l2 tery post l4. To

laterally extending integral for receiving the tapered batthe clampthere is provided a am it having a bore therein for the reception of theconductor l8.

As clearly illustrated in Figure 4 adjacent the vided a laterallyextending annular clamp 8 there is propin 20 having on the ver 32 isprovided with 4 post i4 and by virtue of the shoulder 22. Similarlyadactuating arm 24 is pivlaterally extending arm l6 throughthe'medium ofthe transverse pin 26.

Intermediate the ends of the actuating arm 24 5 there is swivellymounted on the outer side thereof a nut 30 into which there isadjustably threaded the lever 32. As clearly illustrated the leanintegral flattened end portion 34 having a centrally disposed aperture36 for receiving the pin 28- of the annular gripping jaw. g

0n the outer side, adjacent the free end of the laterally extending armit there is provided a stop member 38 which is received in the recess 40in the lowermost locking position of the actuating arm 24.

As clearly illustrated in Figure 1 the annular gripping jaw or clamp 8is placed over the battery slit Ill therein the jaw is adapted toreceive battery posts of substantially any size. The lever 32 is thenscrew-threaded in the nut 30 and the free apertured end 34 placed on thepin 20 between the shoulder and the clamp. Upon a downward pressing ofthe actuating arm 24, the movable free end of the clamp jaw 8 is drawntoward the stationary free end thereof causing the clamp to tightly andclosely embrace the binding post l4 effecting a positive outer endthereof a jacent the clamp an otally mounted to the electricalconnection therebetween. It is to be noted in the event that it isdesired to provide a tighter joint. or to use the terminal for diflerentsize binding posts, this may be accomplished by removing the aperturedend 34 of the lever 32 from its pin 20 and screwing the arm in or out ofthe swivelly mounted nut 30.

Attention is invited .to the relative position of the pins 20 and 26 andthe stop member 38. The pins 20 and 26 being on substantially thelongitudinal axis of the battery terminal, while the 40 I swivellymounted nut 38 and the stop member 38 in the lowermost locking positionof the arm 24 are below the longitudinal axis, so that in the lockingposition of the arm 24 the free end of the lever 32 lies below thelongitudinal axis to the end that the lever 32 tends to rotate theactuposed thereon as are indicated in the prior art or in the appendedclaims.

What is claimed is:-

1. A storage battery terminal comprising a. split clamping jaw having atapered battery Dost receiving bore therein, an integral conductorreceiving arm on said jaw, a pivotally mounted actuating handle on saidam, a. laterally extending pin on the free end of said clamping jawprovided on the outer end thereof with a shoulder, a screw threaded nutpivotally mounted on said handle, a lever, one end of said lever beingapertured and removably secured on said pin, the other end having screwthreads thereon for adjustable screw threaded reception in said nut.

2; A storage battery terminal comprising an annular split clamping jaw,an integral conductor receiving arm on said jaw, an actuating handlepivotally mounted at one end to said conductor receiving arm, alaterally extending pin adjacent the free end of said clamping jawhaving an integral shoulder on the outer end thereof, a nut swivellymounted intermediate the ends of said actuating handle below the pointof pivotal'connection of the handle, a screw-threaded lever having anaperture in one end thereof removably secured on said laterallyextending pin, the other end being adjustably received in the swivellymounted nut, and a stop member on said conductor receiving arm for saidactuating handle.
